Description

  The present invention relates to a vehicle interior member mounting structure for mounting an interior member to a mounted member in a positioned state.

Most of the interior members are positioned by positioning pins with respect to the mounted members in the vehicle interior, and are fixed by screws or the like in that state (for example, see Patent Document 1).
Further, when restricting the movement of the interior member in the rotation direction with respect to the mounted member, a locking portion is provided on the head of the positioning pin, and the positioning pin is fitted into the corresponding positioning hole so that the hole is formed in the locking portion. By pressing the edge, the interior member is positioned in a non-rotating state.
JP 2001-159408 A

  However, if the locking portion is provided at the head of the positioning pin in order to position the interior member in the non-rotating state, the shape of the positioning pin becomes complicated, and the manufacturing cost is likely to increase.

  Accordingly, the present invention is intended to provide a vehicle interior member mounting structure capable of reducing the manufacturing cost by allowing the interior member to be attached to the mounted member in a state where the rotation is restricted with a simple structure. To do.

The invention according to claim 1, which solves the above-described problem, positions an interior member (for example, a closing restriction bracket 13 in an embodiment described later) and attaches a member (for example, an instrument panel 10 in an embodiment described later). And a first positioning pin (for example, a first positioning pin 17 in an embodiment to be described later) having a protruding length and substantially parallel to each other. second positioning pins (e.g., the second positioning pin 18 in the embodiment) provided with a, the interior member, a first positioning hole corresponding to said second positioning pins and the first positioning pin ( For example, the first positioning hole 23) and the second positioning hole (for example, the second positioning hole 24 in the later-described embodiment) described later. Provided, the first of said interior member temporarily held by the positioning pin and said first positioning hole corresponding to the second positioning pins to be fitted into the second positioning hole, the interior member in that state wherein mounted on the mounting member, the protruding length the of the first positioning pin second positioning pins, the long side positioning pin with projecting length (e.g., the first positioning pin 17 in the embodiment) The positioning pin (for example, the second positioning pin 18 in the embodiment described later) on the short side is disposed vertically above the center of gravity in the temporarily held state of the interior member (for example, the second positioning pin 18 in the embodiment described later). The position of the center of gravity G) is a vertical line (for example, an actual state described later) passing through the positioning pin retaining unit (for example, the retaining unit 17a in the later-described embodiment) disposed vertically above. Offset from the vertical line P) to the side of the positioning pins toward the tip, and the tip of the first positioning pin and the tip of the second positioning pin are directed obliquely downward in the vertical direction. It is characterized by.
In the case of this invention, first, the corresponding one positioning hole is fitted to the longer positioning pin of the first positioning pin and the second positioning pin. While adjusting the inclination and displacement, the other positioning hole is fitted to the positioning pin having the shorter protruding length. Thus, when the positioning holes corresponding to the interior member are fitted to both positioning pins, the interior member is temporarily held in a state where the rotation is restricted. The interior member is then attached to the attached member by screws or the like.
In addition, if the positioning pin corresponding to the interior member is fitted to the positioning pin on the upper side and the fitting to the positioning pin on the lower side fails, the interior member is vertically below the holding portion of the positioning pin on the upper side. Attempts to rotate and displace the center of gravity toward the position. For this reason, gravity acting on the interior member acts in a direction intersecting with the upper positioning pin, and the interior member is locked to the upper positioning pin.

According to the first aspect of the present invention, the mounted member is provided with the first positioning pin and the second positioning pin which are different in protrusion length and are substantially parallel to each other, and the positioning holes corresponding to the interior member are provided in both positioning pins. Thus, the interior member can be securely attached to the attached member in a state where the rotation is restricted by a simple structure that is easy to manufacture. Therefore, according to the present invention, the manufacturing cost can be reduced.
Furthermore, in the present invention, since the protruding lengths of the first positioning pin and the second positioning pin are different from each other, after the positioning hole corresponding to the positioning pin having the long protruding length is fitted, the subtle displacement of the interior member is prevented. While adjusting, the positioning hole corresponding to the positioning pin having a short protruding length can be fitted. Therefore, positioning of the interior member can be performed easily and reliably.
In addition, by fitting the corresponding positioning hole to the positioning pin having a long upper protruding length, even if the fitting to the positioning pin on the lower side fails, the interior member is moved upward by its own weight. It is possible to prevent the interior member from falling down. Therefore, according to the present invention, it is possible to improve the assembly workability.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As also shown in these drawings, a closing restriction bracket 13 is attached in the vicinity of both corners on the upper side of the box opening 12 from the back side (the back side with respect to the passenger compartment). The instrument panel 10 and the closing restriction bracket 13 are made of a resin material and formed by molding. In the case of this embodiment, this closing restriction bracket 13 constitutes an interior member in the present invention, and the instrument panel 10 constitutes a mounted member.
As shown in FIG. 3, the front wall 10a in which the box opening 12 of the instrument panel 10 is formed is slanted so that the upper part protrudes toward the vehicle interior side, and a shelf-like shape is formed on the upper part of the front wall 10a. The upper wall 10b is bent and formed.

  Upper support projections 15 to which the upper portions of the closing restriction brackets 13 are fixed are provided on the upper edge portions close to the left and right corners of the box opening 12, and the closing restriction brackets 13 are provided on the side edges close to the left and right corners. A lower support protrusion 16 is provided to which a lower portion of the lower support protrusion 16 is fixed. The abutting surfaces 15a and 16a of the support protrusions 15 and 16 with respect to the closing restriction bracket 13 are set to be inclined in the same direction and substantially orthogonal to the front wall 10a. A first positioning pin 17 protrudes from the abutting surface 15 a of the upper support protrusion 15, and a second positioning pin 18 protrudes from the abutting surface 16 a of the lower support protrusion 16. These positioning pins 17 and 18 are formed in a straight round bar shape so that their extending directions are parallel to each other, and both are formed integrally with the instrument panel 10. Further, the protruding length of the first positioning pin 17 with respect to the abutting surface 15a is set longer than the protruding length of the second positioning pin 18 with respect to the abutting surface 16a.

  As shown in FIG. 2, the closing restriction bracket 13 is formed in a substantially L shape in plan view so as to substantially conform to the corner shape of the box opening 12, and in the box opening 12 at a position corresponding to the inner corner of the L shape. A restriction wall 19 that bulges out is extended. A cushion rubber 20 is attached to the regulation wall 19 so that the back surface of the front panel 11a contacts when the glove box 11 is closed.

  The upper and lower ends of the closing restriction bracket 13 are provided with an upper mounting wall 21 and a lower mounting wall 22 that come into contact with the abutting surfaces 15a and 16a of the upper support protrusion 15 and the lower support protrusion 16 on the box opening 12 side. It has been. A first positioning hole 23 into which the first positioning pin 17 is fitted is formed in the upper mounting wall 21, and a screw fixing hole (not shown) is formed at a position close to the positioning hole 23. Yes. Similarly, a second positioning hole 24 into which the second positioning pin 18 is fitted is formed in the lower mounting wall 22, and a screw fixing hole 25 is formed at a position close to the positioning hole 24. Has been. In the figure, reference numeral 26 denotes a screw for fixing the upper mounting wall 21 and the lower mounting wall 22 to the upper support protrusion 15 and the lower support protrusion 16.

  Further, the closing restriction bracket 13 is temporarily held by the instrument panel 10 by fitting the first positioning hole 23 and the second positioning hole 24 to the first positioning pin 17 and the second positioning pin 18. However, the position of the center of gravity G of the closing restriction bracket 13 in the temporary holding state is offset to the side of the positioning pin 17 facing the tip of the vertical line P passing through the holding portion 17a of the first positioning pin 17. Is set to

  The closing restriction bracket 13 is provided with a plurality of reinforcing ribs 30 projecting from almost the entire area thereof and joined to the corner portion of the box opening 12 to reinforce the edge of the box opening 12.

When the closing restriction bracket 13 is attached to the instrument panel 10, the closing restriction bracket 13 is set from the back side of the instrument panel 10 to the upper corner of the box opening 12. The first positioning hole 23 of 21 is fitted to the first positioning pin 17 of the upper support protrusion 15. At this time, the projecting length of the first positioning pin 17 is set to be sufficiently longer than the thickness of the upper mounting wall 21, so that the closing restriction bracket 13 defines the first positioning hole 23 as the first positioning pin. A relatively stable holding state can be maintained by inserting it into the front 17 once from the front. Next, from this state, the closing restriction bracket 13 is adjusted by shifting the lower end side about the first positioning pin 17 to slightly bend and deform the lower mounting wall 22 while changing the second positioning hole 24 to the second positioning pin. 18 is fitted. At this time, since the second positioning pin 18 has a short projecting length with respect to the first positioning pin 17, the second positioning pin 18 can be easily fitted into the second positioning hole 24 by slightly bending and deforming the lower mounting wall 22. can do.
Thus, when the first positioning hole 23 and the second positioning hole 24 are fitted to the first positioning pin 17 and the second positioning pin 18 on the instrument panel 10 side, the closing restriction bracket 13 is moved to the instrument panel. 10 is temporarily held in a state of being accurately positioned at 10.

  Next, from this state, the upper mounting wall 21 and the lower mounting wall 22 of the closing restriction bracket 13 are fixed to the upper support protrusion 21 and the lower support protrusion 22 on the instrument panel 10 side by screws 26.

  As described above, in this embodiment, the first positioning pin 17 and the second positioning pin 18 having different protruding lengths are provided on the instrument panel 10 side, and the closing restriction brackets are provided on these positioning pins 17 and 18. Since the closing restriction bracket 13 can be positioned in the non-rotating state by fitting the positioning holes 23 and 24 on the 13th side, the shape of the positioning pins 23 and 24 can be simplified to reduce the manufacturing cost. it can. Specifically, since the positioning pins 23 and 24 have a straight round bar shape, the positioning pins 23 and 24 can be easily formed by molding as in other parts of the instrument panel 10.

  In this embodiment, since the protruding length of the first positioning pin 17 positioned on the upper side is set longer than the protruding length of the second positioning pin 18, the first protruding pin having a long protruding length is used. The first positioning hole 23 is first inserted into the positioning pin 17 and the second positioning hole 24 is fitted to the second positioning pin 18 while performing a fine position adjustment, whereby the closing restriction bracket 13 is instrumented. The panel 10 can be easily temporarily held. Therefore, the positioning operation can be facilitated.

Furthermore, in the case of this embodiment, in addition to the projection length of the first positioning pin 17 being set sufficiently long, the position of the center of gravity G in the temporary holding state of the closing restriction bracket 13 is the first upper side. The positioning pin 17 is positioned on the side facing the tip of the positioning pin 17 with respect to the vertical lower side P passing through the holding portion 17 a of the positioning pin 17. Even if the fitting between the positioning hole 24 and the second positioning hole 24 fails, the closing restriction bracket 13 can be engaged with the first positioning pin 17 to prevent the instrument panel 10 from falling off. That is, when the fitting of the second positioning hole 24 fails in a state where the first positioning hole 23 is fitted to the first positioning pin 17, the closing restriction bracket 13 uses the first positioning pin 17 as a fulcrum. The first positioning pin 17 is caught by the rotation due to its own weight, and dropping from the instrument panel 10 is restricted.
For this reason, even if the fitting of the second positioning hole 24 to the second positioning pin 18 fails once, the fitting of the second positioning hole 24 again without reinserting the first positioning hole 23. Can be done. Therefore, the positioning operation of the closing restriction bracket 13 can be performed efficiently.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in the above embodiment, the mounting structure according to the present invention is applied to the mounting portion for mounting the closing restriction bracket 13 of the glove box 11 to the instrument panel 10, but the mounting structure according to the present invention is not limited thereto. The present invention can also be applied to attachment parts of various interior members.
